Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sat Apr 24 2021

Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 140W. The following information is
based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0240 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from 08N78W to 08N110W. The ITCZ 
continues from 08N110W to 05N120W to 05N140W. Scattered moderate
convection is noted from 03N to 07N E of 90W. Scattered moderate
isolated strong convection is observed from 03N to 10N between 
95W and 121W, and from 06N to 10N between 130W and 138W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge extends from high pressure northwest of the region to
between Los Cabos and the Revillagigedo Islands. The pressure
gradient between this ridge and lower pressure over Mexico is
supporting moderate to fresh winds west of the Baja California
peninsula. Gentle to moderate winds prevail elsewhere over the
open waters off Mexico, with light to gentle winds over the Gulf
of California. Seas are in the 5 to 7 ft range primarily in SW 
swell over the open waters, with seas in the 1-3 ft range over
the Gulf of California.

For the forecast, the winds off Baja California will diminish 
into Sat as the high pressure west of the area weakens. 
Meanwhile, long period southerly swell will maintain seas of 5-7 
ft in open waters through Sat night before subsiding. A trough 
will move across Baja California Mon and Tue, followed by 
moderate to fresh NW winds. 

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and 
WITHIN 750 NM OF ECUADOR...

Gentle to moderate winds prevail over and downstream of the Gulf
of Papagayo. Light to gentle winds persist elsewhere. Seas are 
in the 6 to 8 ft range over and downstream of the Gulf of 
Papagayo, and 5-6 ft elsewhere. 

For the forecast, fresh gap winds will pulse mainly overnight 
across the Gulf of Papagayo through Sun, then becoming fresh to 
strong early next week. The long period cross- equatorial 
southerly swell will subside through Sat night. Another smaller 
swell will move into the region by mid week.

REMAINDER OF THE AREA...

The pressure gradient between 1025 mb high pressure located 
northwest of the forecast area and lower pressure in the 
vicinity of the ITCZ supports a large area of moderate to locally
fresh trade winds from 08N to 20N west of 125W. Seas are 6 to 8 
ft across this region. High pressure will weaken tonight as a 
cold front approaches from the northwest. High pressure will 
build in the wake of the front, and will dominate the forecast 
waters during the upcoming weekend into early next week.
